AT/ATX

Just wondering if there is a good guide which describes the differences between the 2 since I am still a little vague, and I am taking the test on Thursday

For what I know the Diff's between from what I studyed from the A+ book that the P8 and P7 or P9 has to be together, and on the ATX its just one thing, and AT is older and ATX is new types, ATX comes with sound, and video. If there is other diff's then let me know. (This is just the top of my head right now) and I haven't find any studyed guilds about this.

the major differences are the power connection from the psu to the motherboard, as Jamesfrovich said, atx uses ps/2 keyboard connector as norm, the cpu is moved closer to the psu for better airflow, the specialised panel at the back with the ports (as opposed to the at format of having serial and parallel ports, etc in the chassis or back plates) and the sof-power connector on the motherboard (as opposed to the at power going directly from the button on the front of the case to the psu).
